摘要
在工作状态下对大型天线面型进行高精度测量与调整是当前国内的一个难题,将基于专业数码相机的摄影测量系统应用于大型天线的检测中:采用回光材料制作人工标志,利用编码标志来完成摄站的自动定向和同名点匹配,经光束法平差解算点的坐标,点位的测量精度优于0.11 mm,面型的计算精度达到0.4 mm,并与全站仪的测量结果进行比较,进一步验证了上述测量结果的正确性。
We check a large antenna by the high accuracy digital photogrammetry technology based a high accuracy special digital camera, We make retro-reflective targets with special material; realize the orientation of all camera stations automatically and match homologous points by coded targets; calculate unknown points＇s coordinates by bundle method, The positional accuracy achieves 0.11 mm. And the surface fitting accuracy achieves 0.4 mm. Finally, we compare the above results with total station instrument＇s to approve the results right.
